Comparison of Prosthetic Femoropopliteal Bypass Versus Viabahn Endoprosthesis for Treatment of Symptomatic Femoral Artery Occlusive Disease

This study has been completed.

Collaborator:
W.L.Gore & Associates
Information provided by:
Texas Vascular Associates
ClinicalTrials.gov Identifier:
NCT00693823
First received: June 3, 2008
Last updated: June 6, 2008
Last verified: June 2008
  Purpose
This study is a comparison of two different ways to treat blockage in the artery of the thigh. The first is an older way with incisions in the groin and just above the knee. A plastic tube is then inserted to make a bypass from the groin to the knee. The second treatment offered is through a needle hole in the groin. A thin plastic tube covering a metal stent is inserted into the artery and released to bypass the blockage from inside the artery. No incisions are needed. Patients are enrolled and then selected for one treatment method or another by chance. The patients will be followed for two years to see how the two different treatment methods work compared to each other.

Condition Intervention

  Eligibility

Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:Patients that had atherosclerotic stenotic or occlusive lesions of the superficial femoral artery with no significant aorto-iliac disease. The infra-popliteal segment had to be patent with at least single vessel run-off to the ankle. Patients had to be acceptable surgical candidates in the event they were randomized to the surgical arm.

Exclusion Criteria:Non-operative candidate,Contraindication to IV contrast use, Planned surgery with venous conduit, previously stented segment of the superficial femoral artery, poorly compliant patient.
